Title:
SEISMIC ISOLATION DEVICE AND SEISMIC ISOLATION STRUCTURE OF LIGHT-WEIGHT BUILDING
Document Type and Number:
Japanese Patent JP3174859
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a simple seismic isolation device, in which the function of seismic isolation can be brought out sufficiently.
SOLUTION: The seismic isolation device consists of an elastic body 2 integrally molded of an elastic material cylindrically and in which an inserting hole is formed at the center in the height direction, and a rod-shaped body inserted into the inserting hole formed to the elastic body 2. The seismic isolation device has one disk 4, which is fixed onto the underside of the elastic body 2 and of which the underside is installed onto the top face of a foundation 14, the other disk 5, which is fastened onto the top face of the elastic body 2 and of which the underside of a sill 15 is mounted on a top face, one shaft body 6 projected to a lower section from the underside of one disk 4, the other shaft body 7 projected to an upper section from the top face of the other disk 5 and put into an inserting hole shaped to the sill 15, an anchor bolt 10, in which an upper end is fastened onto one shaft body 6 and which is buried into the foundation 14, and a fixing means fixing the other shaft body 7 onto the sill 15.
